New Yeti SB140 trail bike boasts 140mm of frame travel and updated Switch Infinity link

The new trail bike will replace the outgoing SB140 and SB130. It is similar in rear travel to the previous model, but has been developed around a 29in wheel size, as was the SB130. However, the SB140LR will also be available in a 27.5in wheel size.

The model will be available in two build types (the SB140 and the SB140LR) and two types of modulus for the carbon frame. Availability is from 20 January 2023.

The Lunch Ride (LR) will feature a more aggressive 160mm front fork, as opposed to the SB140’s 150mm. Other differences include chunkier tyres and more powerful brakes on the Lunch Ride.

Geometry updates

SB140

Yeti has increased the front centre by 7mm, from 795mm on the previous model to 802mm on the new SB140 in size large. Reach remains similar, increasing by 0.5mm.

Like all recently released Yeti models, the SB140 will have size-specific chainstay lengths and seat tube angles. Chainstay lengths range from 436mm to 444mm, with the aim of giving proportional geometry across all sizes.

Actual seat tube angles range from 72.2 degrees to 73.7 degrees, but the effective seat tube angle remains the same at 77.5 degrees on all sizes – saddle-height dependent.

Seat tube lengths have been reduced to allow for longer dropper posts on all models. Yeti has added an extra-extra-large frame and removed the extra-small size from its line-up. The new small size has a 10mm longer seat tube than the previous extra-small. The head tube angle remains 65 degrees.

SB140LR

Similar to the SB140, the SB140LR has a longer front centre than its predecessor, increasing 6mm from 800mm to 806mm on a size-large frame. The reach is marginally shorter by 0.1mm.

Chainstay lengths range from 436mm to 444mm, again with the aim of giving proportional geometry. Seat tube angles range from 71.8 degrees to 73.3 degrees, with the effective seat tube angle 77 degrees. The head tube angle remains 65 degrees.

The Lunch Ride will also be available with 27.5in wheels. There has been no word from Yeti on the changes this will make to the geometry.

SB140 and SB140LR suspension details

Both bikes will feature 140mm of frame travel with a 14 per cent leverage rate controlled by Yeti’s Switch Infinity suspension system. The SB140LR will use a Fox Float X, as opposed to the Float DPS seen on the SB140.

The system works by mounting the main pivot to a ‘shuttle’. The shuttle moves up and down on two Kashima-coated stanchions embedded in the frame, giving a rearward axle path to the suspension stroke. Yeti says this improves pedalling performance.

Yeti says it has altered the architecture of the frames by fitting the Switch Infinity into a tighter package. Ground clearance and ‘chassis’ stiffness are said to have increased with the re-design.

T-series models will be equipped with an updated Switch Infinity system, which Yeti says will have improved seals, bearings and hardware.

Frame refinements

Yeti has revised its down tube protection, now using a two-layer system. It says the rubber under-guard provides a cushion against the frame, while an external hard cap provides impact protection. The system is replaceable, and the hard cap is removable to aid in cable routing.

Yeti claims it has eliminated rattles and cable rub by fitting secure ports to internal cable tubes.

The threaded aluminium bottom bracket is now co-moulded into the frame’s carbon layup, as seen on the new SB160 and SB120. Yeti says this makes the interface more durable and easier to service.

Yeti SB140 spec and price

There will be five build options for the SB140. Three of these will be built around the top-spec, higher-modulus Turq-series frame. The other two will use the C-series frame. T-series bikes will also receive a Fox Transfer dropper post.

All SB140s will feature Fox 36 forks with 150mm of travel and be available in Turquoise, Sangria, Sage and Raw Carbon.
